TROLLEY-WHEEL.

Specification of Letters Patent.

Patented Feb.'18, 1908'.

Application filed July 18. I907- Serial No. 384-421.

To all whom it may concern:

Be it known'that I, EDWARD J. HARRISON, a; citizen of the United States, residing-at South ,Bend, in the county of- St. Joseph and State of Indiana, have invented certain new- -and useful Improvements in Trolley-Wheels, of which the following is a specification. This invention relates to trolley wheels.

One object of the invention is totprovide a trolley wheel embod g such character istics that it and the wil wire maybe continuously su plied with a lubricant to reduce the friction between-the wheel and Wire and to supply a lubricant to the trolley wire for the ur ose hereinbefore set forth and for the forming upon the under surface of the trolley withoutimp airing the normal conductivity of the, current from the wire into the tro ley Wheel. 'I With the above and other objects in view, the present invention consists in the combination and arran ement of parts hereinafter more fully descri ed, illustrated in the accompanying drawings a and particularly pointed out in the appended claims, it'being understoodthat changes may be made in the form, proportion, size and minor details Without-departing from the spirit or sacrificin any ofthe advantages thereof. a

1 %n the accompanying drawings, 1 illustrates a trolley Wire with which'cooperates a trolley wheel embodying my invention, the trolley wheel being shown partly in elevation and partly in section.

Referring now more particularly to the accompanying drawin s, the reference character 1' indicates atro'ley wire and 2 a trolley pirovided as usual with a hub 3 adapted to wor "upon the axis 4, there being a series ofspokes 5 radiating from the hub 3 to'the grooved flanged portion 6 of the .'wheel, the trolley wire 1 fitting in the grooved flanged portion 6 in the usual manner.

The hub 3 of myimproved wheel'is provided with anarcuate recess 7 provided with a screw threaded of enin I riphery of the hub 1n which fits theredu'ced screw threaded portion 9 of the lubricant-cup 10, there being a passage 11, leadingfrom" the er purpose of preventing ice-from 1 8 through the pesaid recess.

7, so that lubricant (not shown) coir-fined within the cup 10 may be forced from the latter by operating the closure-12 through the passage 10 into said recess 7. The lubricant may pass from the recess 7 through the duct 13 to the axis .4 and also through the ducts 14 extending through two or more of the spokes 5 of the Wheel to the grooved flanged portion 6 of the wheel from which latter it may be'su plied to the'trolley wire 1 for the purpose 0 reducing the friction. between the .wheel and wire and also todiminish the wear between the wheel and wire and to prevent tion between t e wire and the wheel;

It-willnow be understood that the lubricant is preferably of a semi-solid consistency and that it is forced from the cup 10 by'theclosure 12 provided witha cone portion 15 adapted to insure forcing of the lubricantinto. the recess 7 When the lubricant reaches the recess 7 the continued rotation of the wheel 6 under the propulsion of the car (not shown). will cause the axis 4 and the periphery of'the wheel .to be su plied with the lubricant. Since the periplibry of the wheel'is supplied with the lubricant it neces- 'the formation of ice upon'the wire withoutnecessarily impairing theelectncal connecsarily follows that the lubricant will be' iven to the trolley wire, and in the use of a a'rge number of cars continuously passing over. a given territo and using m improved wheel, the trolle wire will be We lubricated with exce tiona Y advantages in cold weather, as the oi Will positively revent ice from forming under the lower su1ace of the trolley. at .is claimed is:

1. A trolle wheel including a flanged periphery an hub, a recess formed in the ub, a lubricant cup mounted upon the hub and communicating with said recess, and ducts communicating with the recess and. l'eadi to the eriphery of the wheel.

2. lie com ination with a trolley .wire

and trolley wheel, the wheel having a recess 3'. The combination a trolley io's and a trolleywheel, the wheel including'a' hub provided with a recess, and communicating ducts between the recess and periphery of the wheel, the ducts being formed in spokes of the Wheel, of a lubricant cup carried by the Wheel and communicating with said recess.

In testimony whereof I have signed my name to this specification in the presence of two subscnblng wltnesses.
